FUNNEL-COCK FOR HOT-WATER HEATING SYSTEMS.

SPECIFICATION forming part of Letters Patent N0. 759,623, dated May 10,1904:.

Application filed October 14,1903.

To all whom it may concern:

Be it known that I, OLIVER LINK, a citizen of the United States,residing at St. Charles, Missouri, have invented a certain new anduseful Improvement in Funnel-Cocks for Hot- I/Vater Heating Systems, ofwhich the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, formingpart of this specification, in which-- Figure 1 is a longitudinalsectional view through my improved funnel-cock, and Fig. 2 is across-sectional view.

This invention relates to a new and useful improvement in funnel-cocksfor hot-water heating systems designed especially for use in connectionwith railway rolling-stock.

The object of this invention is to simplify the construction offunnel-cocks and to utilize the funnel on the cock as anoperating-handle.

With these objects in view the invention consists in the construction,arrangement, and combination of the several parts, all as will behereinafter described, and afterward pointed out in the claims.

In the drawings I have shown a tank to which the funnel-cock is attachedby dotted lines and indicatedthe same by the numeral 1.

2 indicates the threaded stem or the funnelcock, which is provided witha passage 3, having ports 4 and 5. This stem is also provided with avent-opening 6.

7 indicates a hub for the funnel, which is held in position by anappropriate nut and washer secured on the stem of the funnel-coek in awell-understood manner. This hub 7 is provided with a passage 8, whichis designed when the funnel is in an upright position to 40 registerwith the vent-passage 6; but when said funnel is in other than anupright position the vent-passage is closed.

9 indicates the funnel secured to the hub 7, whose lower end terminatesin a port 10, adapted to register with the ports 4 and 5.

In practice when it is desired to fill the system the funnel is turned.to the position shown in Fig. 1, wherein it is upright. In this po-Serial No. 177,022. (No model.)

sition the vent 6 is opened, and the ports 4 and 10 register. Liquid maynow be poured 5 into the funnel 9 and enters the tank through thepassage 3. A suifieient quantity of liquid is introduced to overflow thevent-opening 6, and as soon as the operator concludes that he has filledthe system about the desired waterline he moves the funnel to theposition shown in Fig. 2, where the port 10 registers with the port 5.In this position the surplus water in tank 1 will flow through passage 3and out of the funnel to the exterior, the water reaching the desiredlevel by this means. When the surplus water has been drawn off, thefunnel is moved to the lower position. (Shown in dotted lines in Fig. 1,wherein both ports 4 and 5 are closed.) In this position of the t'un- 5nel no dirt, dust, or einders can accumulate to interfere with theaction of thevalve. To determine the upright and lower positions of thefunnel, 1 preferably insert a pin 11 in the stem of the cock and providethe hub 7 with shoul- 7 O ders 12 on each side, which cooperate with thepin and arrest the tunnel in its upright and lowered positions.

I am aware that minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a funnel-cock, the combination with a stem having a port openingthrough its upper face and through its side, and a funnel 5 having asingle port designed to register with either of said ports in the stem,said funnelcoek having an opening coinciding with an opening in thefunnel, which openings are adapted to register when one of the ports ofthe stem registers with the opening in the funnel and closed when theother port in the stem registers with the port in the funnel, for thepurposes described.

2. In a funnel-cock, the combination with a 9 5 stem having a passage 3,ports t and 5, and a vent-opening 6, of a funnel rotatably mounted onthe stem and having a passage 10 de-' signed to register with the ports4 or 5, and an opening 8 designed to register with the vent-passage 6,and means for arresting the funnel in its upright and lowered positions;substantially as described.

3. In a funnel-cock, the combination with a stem having passage 3 andcommunicating ports 4 and 5, and a vent-passage 6, of a funnel 9 havinga hub portion? rotatably mounted on the stem, said funnel having apassage 10 designed to register With the ports I or 5 when said funnelis moved in an upright and
